Recharging procedure
1. Temperature range for recharging:
+ 10 °C to + 35 °C (+ 50 °F to + 95 °F)
2. When the AC adapter is initially connected,
the LED on the instrument lights continuously.
3. After 4 hours of charging, the AC adapter
switches to a pulsed, long-term charging
mode (indicated by the LED flashing every
15 seconds).
Note:
The charging system is designed to prevent
the battery from overcharging and minimizes
the lazy-battery-effect. To maintain maximum
battery capacity, it is best to charge the bat-
tery only when the slowly-flashing or quickly-
flashing LED indicates charging is needed.
The instrument can be used during recharg-
ing.
If the LED does not light up during charging
see chapter 'Troubleshooting' ( page 18).
